This time, transform into a hero to protect your fortress from alien creatures in Criatures Defense.
Be ready to defend your fortress against powerful waves from many different units.
They form huge waves of dangerous enemies that will obliterate your fortress if you don't stop them. Use the main gun to shoot them; the additional system will do it automatically. Activate the weapon from the bottom panel to attack.
Try not to let them get close to your fortress. Aim accurately and destroy as many of them as possible.
Have fun and good luck!
